Hi!


I am observing occasional/intermittent error in the EPICS IOC running on arm linux.

https://bugs.launchpad.net/epics-base/+bug/541371

This is a long standing issue, which no one has so far been able to isolate or reproduce.

By chance have you noticed any pattern in when this occurs?

A call to 'assert(ev_que->evque[ev_que->putix] == EVENTQEMPTY)'


     by thread 'CAS-client' failed in ../../../src/ioc/db/dbEvent.c line 781.


EPICS Release EPICS R3.15.6.

Please E-mail this message to the author or to tech-talk at aps.anl.gov


Calling epicsThreadSuspendSelf()

Do you have any insights on how to avoid this error?



Thank you！
